What is the catalyst for the decomposition of hydrogen peroxide?
manganese sulfide
What is the product of the reaction between calcium hydroxide and hydrogen sulfide?
Calcium Sulfide and water
What evidence was there that a chemical reaction was taking place in the decomposition of hydrogen peroxide?
The decomposition of H2O2 is exothermic and oxygen is released.
Sodium hydrogen carbonate decomposition reaction?
Na2HCO3 -------- Na2CO3 + H2O + CO2
What are the products of the decomposition reaction of hydrogen peroxide?
The products of the decomposition of hydrogen peroxide are water and oxygen, as shown in the following equation: 2 H2O2 → 2 H2O + O2
What is the catalyst for the decomposition of hydrogen peroxide?
manganese sulfide
What is the product of the reaction between calcium hydroxide and hydrogen sulfide?
Calcium Sulfide and water
What type of reaction occures when a sample of the compound selenium sulfide which broke down into selenium and sulfur is heated?
This is a "decomposition" reaction.
What shows a chemical reaction in which magnesium and hydrogen sulfide are the reactants and magnesium sulfide and hydrogen are the products?
The chemical equation Mg + H2S -> MgS + H2.
What evidence was there that a chemical reaction was taking place in the decomposition of hydrogen peroxide?
The decomposition of H2O2 is exothermic and oxygen is released.
What type of reaction is Mg O2MgO?
Thermal decomposition. MgCO3(s) ==heat==> MgO + CO2
What are the products of the decomposition reaction of hydrogen peroxide?
The products of the decomposition of hydrogen peroxide are water and oxygen, as shown in the following equation: 2 H2O2 → 2 H2O + O2
Sodium hydrogen carbonate decomposition reaction?
Na2HCO3 -------- Na2CO3 + H2O + CO2
Is silver tarnishing a physical change?
No, it is a chemical change. The tarnish seen on silver is silver sulfide which formed by the silver reacting from small amounts of hydrogen sulfide in the air. So silver sulfide has been created by a chemical reaction.
What kind of a chemical reaction happens when hydrogen peroxide can break apart to form water and oxygen gas?
That would be a decomposition reaction. The equation for it would be: 2H2O --> 2H2 + O2 The process called electrolysis will do this.
Is Ag tarnishes physical property or chemical property?
It is a chemical process - a reaction with hydrogen sulfide.
What shows a chemical reaction in which hydrogen sulfide and oxygen are the reactants and sulfur and what are the products?
"Which" implies choices... Where are they??
